Sanchez and most of the other passengers were asleep when the bus, headed to LA from the Red Earth Casino in Salton City, crashed into the truck on Interstate 10 so fast the truck's trailer was embedded 15 feet into the bus.

The California Highway Patrol said Sunday the bus was operated by Los Angeles-based USA Holiday. A phone message The Associated Press left for the company was not immediately returned. A Facebook message from USA Holiday said it did not have much information about the crash.

Neighbors told NBC4 that the owner of the bus company lived in Alhambra and was a father who was running a small family business.
